"Just went through the exact same thing on my 2018 Vegas this past summer. They thought it was the solenoids, changed those, not it. After many weeks and lots of head scratching, figured out the switch (that cuts off the house batteries to the coach) had gone bad and was NOT cutting anything off and draining all of the batteries."
I'm also having problems with my "store" switch in my 2018 24.1 Axis. I have to cycle the switch TWICE for it to disconnect power. I hear the relay click on first actuation, but I have to cycle the switch back on and off a second time before power actually disconnects. Is this the same problem you were having?
